If you go with the black bed, get a rustic and in fall colors night stand, that will stand up with the orange. Or that particular bedspread has golds, browns, and other shades... you might even be able to work a fall leaf red (sort of a dark faded red) in there for the night stand and the red into more accent pillows that would take the Halloween away. Stay away from bright limey greens and not picking up more of the orange or black and you could make it work well.

I like the idea of bringing some black into your room. I think lamps with black shades would look very nice and because you love pink you could get black chairs with pink cushions. You need to tie in the pink in other areas of your livingroom but I would not overdue it. It's a beautiful shade of pink but too much of it would be too overpowering in my opinion. Post some more pictures of your room if you can.

Adding taupe or beige to the walls, in most hues, would blend in too much with the draperies. I love the lavender in the bedding. It would pull the room together if you were to choose a grey paint that had elements of lavender or berry and silver. The color would be subtle, neutral, relaxing as well as refined. This slight shimmer will pull out the subtle nuances in the marble. As the headboard is already so interesting, it would be too busy to add anything too ornate on the wall. To open up the room and increase the light, you could hang a mirror. I would select an Art Deco style with metallic accents to continue pulling together the room. The marble is lovely, but combined with the sleek lines in the bed and bedding it creates a very smooth appearance. To create warmth, it is necessary to add additional texture. I would add a soft, plush or high pile area rug by the bed. How nice would it be to step out of bed on to that?

The room has exquisite bones: the windows, flooring and decorative crown molding. If simplicity is what you want but with a bit more personal taste, I suggest the following: 1) paint the walls white that has a soft, warm undertone such as Benjamin and Moore's moonlight white or Dove. (Or try any good paint store for help on picking the right white color.) Paint the molding a stark white with an egg shell or gloss finish. 2) keep the bed covering as is. I love the warm colors and mixed patterns. If you do want more comfort, yes add a thicker mattress. Can you get a fabric similar for the table top? Or just remove the fabric from the table top, painting or stenciling it with a similar pattern. (see #5 below for where to look for stencils.) 3) Move the table to the head of the bed, add a modern lamp and lots of books or other meaningful, personal items. 4) Add a comfy chair or as suggested above, pile lush floor pillows where the table is, under the window. Use complementing or solid color fabric on the floor pillows or chair. Add a small table with more lighting. (See my most popular post on Floor Pillows. Towards the end you will see examples of suitable floor pillows. Or just do a search here on Houzz and the internet.) 5) Make a dramatic statement above the bed with a very large painting. Select with care based upon your personal taste: abstract, minimal but with a hint or some of the colors found in the bedding fabric. It doesn't have to be centered, a little off centered will do since there appears to already be something on the wall above the bed. Do add a soft art lamp above the painting. (If you don't have money for the painting, purchase a very large canvas, take your time and create it yourself (collage it, play around with paint on paper before adding it to your canvas, stencil it, etc.--but have fun and make it personal) Here's a great place for getting a wide range of designs for stenciling: Cutting Edge Stencils. Note you don't have to take the design all the way to the edge of the canvas! 6) Add a small (wool) flokati rug in front of the bed. Get the kind that comes from Greece, it has long-fibers and a plush pile. These rugs are to die for when it comes to comfort and texture--and they're inexpensive. Take a look and if you like it, be sure to get wool: Flokati Rug.Net. These ideas will give you lots of varying textures to get rid of the boredom; contrasting colors for depth and drama; play up the wonderful architectural elements already found in the room; personalize it with what you love; and still, keep it simple and beautiful. Use soft lighting. Good luck!
